【摘要】 本文采用计算机系统仿真的方法,研究了应用相敏光放大器(PSA)作为在线放大器的采用平均孤子传输方案的光孤子通信系统中,泵浦光与信号光之间的相位漂移、光纤色散对光孤子通信系统传输性能的影响。仿真的结果表明:泵浦光与信号光之间的相位漂移将导致孤子幅度的下降;由于PSA增益的相敏特性,光纤色散导致孤子脉冲主瓣幅度下降,脉宽展宽,出现旁瓣。更多还原

【Abstract】 In this paper, the effect of phase-shift between pumping and signal light and optical fiber dispersion parameter on the performance of average-soliton transmission system using PSA as in-line amplifiers has been analyzed theoretically by computer simulation.Our simulation results show that phase-shifting between pumping and signal light in PSA results in descending of soliton pulse amplitude and its width broadening. Because of the phase-sensitive nature of PSA’s gain, fiber dispersion will also cause soliton pulse amplitude descending and its width broadening.更多还原
